The advertisement states
Q-switched (photoelectric switch) and MOPA construction
These are two different animals, mutually exclusive as far as I know… 
Spot Size: 0.03*0.06mm
Peak Power: 7kW
You should be happy to know you have a 7kW laser 
I’d think this would be here now, as it also states that you can adjust laser power and adjust pulse frequency
With a MOPA you can also adjust pulse duration.
A great video from Laser Everything explains interval and how you can do great work with any laser… They do it on a fiber.
Bonus for you 
Might want to check out some of @Bulldog work with photographs… great and done with a fiber…
NWT method…
That’s great, a really neat machine, I hope you tell us more about it as you move forward… I’ve had my eye on these. I like the LaserPecker 4, but it was a bit lame in many areas. It was also a yag q-switch type.
Good luck, thanks for posting…
